Emergency power supply is mainly composed of an inverter, a transformer, a charger, a battery pack, a conversion relay, a battery circuit breaker, a mains input circuit breaker, and an output branch circuit breaker. When the utility power is normal, the mains power is directly output; meanwhile, the battery is charged by the charger; when the mains power is interrupted or lower than the set limit, the inverter starts to work, and the direct current of the battery is converted into AC power supply by the inverter and transformer to supply power to the emergency load.
